Suppose that \( A \) and \( B \) are two \( n \) by \( n \) matrices satisfying the relation \( (A-B)(B+A)=A^{2}-B^{2} \). Which of the following statement is correct? \( A B-B A=0 \), where \( O \) is the \( n \) by \( n \) zero matrix None of the given options \( A B=I_{n} \), where \( I_{n} \) is the \( n \) by \( n \) identity matrix \( A \) and \( B \) are identical matrices
